Nine less than nine times a number is at least thirty-six

let "a number" = x; at least = ≥

9x - 9 ≥ 36

Isolate the x. Do the opposite of PEMDAS.

First, add 9 to both sides

9x - 9 (+9) ≥ 36 (+9)

9x ≥ 45

Divide 9 from both sides to isolate the x.

(9x)/9 ≥ (45)/9

x ≥ 45/9

x ≥ 5

x ≥ 5 is your answer
